Angie’s List states that less than 5% of the companies on Angie’s List received the award in 2018. We were honored to be a recipient of the SSA in 2019.

Are you covered by a maintenance agreement?

If your HVAC system is not covered by a maintenance agreement, you may be fully out-of-pocket every time a technician comes by your home to inspect your A/C or repair it. D&H Air Conditioning has created a very advantageous inspection and service plan called Guardian Plan (learn more about it here), which gives you access to our technicians on a priority basis, as well as discounts on parts and labor.

Priority service is an awesome benefit when your A/C breaks down in 100°F temperatures. When you call, we already know you are a Guardian Plan member, so you get first-in-line scheduling, which means the difference between roasting in your home for a full day, and being cooled off again within hours.

You can learn more about the benefits of the Guardian Plan by following the link above, or just enter your first and last name and your phone number in the fields below to request a call-back by our of our technical reps. We will answer any question you may have about our inspection and performance tune-up plan.
